Abstract: PURPOSE:To equalize the melting and solidification of latent heat accumulating bodies by a method wherein a heat medium is flowed into, and out from, a casing having the latent heat accumulating bodies arranged therein, in such a manner that the circulating direction of the heat medium is reversed. CONSTITUTION:In a condition in which a pump 4 is operated and a pump 8 is stopped, the heat medium 6 is flowed into the casing 3 in the direction of the solid line arrow and a heat exchange operation is carried out efficiently starting from the heat accumulating body 1 near an inlet 5. Then, after a lapse of a predetermined time, the pumps 4 and 8 are switched to each other and the heat medium 6 enters the casing 1 in the direction of the dotted line arrow. Consequently, the heat accumulating bodies 1 are melted efficiently beginning from that arranged near the inlet port 7. In this case, the switching between the pumps 4 and 8 is repeated periodically. Thus the heat accumulating bodies throughout the casing 3 are melted uniformly. As regard the solidification of the heat accumulating materials, the same process takes place. Accordingly, it is possible to improve the heat accumulating and heat discharging properties of the heat accumulating device.
